Exercise
$\left(x+2y\right)dx-3ydy=0$
Step-by-step Solution
Learn how to solve simplification of algebraic fractions problems step by step online. Solve the differential equation (x+2y)dx-3ydy=0. We can identify that the differential equation \left(x+2y\right)dx-3y\cdot dy=0 is homogeneous, since it is written in the standard form M(x,y)dx+N(x,y)dy=0, where M(x,y) and N(x,y) are the partial derivatives of a two-variable function f(x,y) and both are homogeneous functions of the same degree. Use the substitution: y=ux. Expand and simplify. Integrate both sides of the differential equation, the left side with respect to u, and the right side with respect to x.

Final answer to the exercise
$-\frac{3}{4}\ln\left|\frac{y}{x}-1\right|-\frac{1}{4}\ln\left|\frac{3y}{x}+1\right|=\ln\left|x\right|+C_0$
